Theros Ironfeld: The Warriors, Book 4

A young boy stood on the dock of his fishing village and watched the minotaur war barge approach. It would change his life from a lad who would have grown to follow in the footsteps of his father, to the greatest weaponsmith in the history of Krynn. As a boy, Theros Ironfeld was captured and pressed to service under the minotaurs. As a man, he first fought draconians to a standstill in Solace, and later, by mysterious means, acquired a silver arm. And when the evil dragons came to conquer, he was the only man who could forge the fabled dragonlances necessary to defeat them. The Warriors series details the exploits of the heroes and villains of the War of the Lance.
